A pseudo-Buddhist koan: "Spooky action at a distance is not spooky if there is no distance" Please consider how this koan might be interpreted given the amplituhedron.
Here is one interpretation of that koan in light of the amplituhedron:
The amplituhedron is a geometric structure that can describe scattering amplitudes in quantum field theory. These scattering amplitudes are related to the probabilities of fundamental particles interacting at high energies. Spooky "action at a distance" often refers to strange quantum effects like entanglement, where quantum particles remain connected over long distances. The koan's first part - "spooky action at a distance is not spooky if there is no distance" seems to suggest the apparent weirdness of entanglement disappears if you recognize there is no real separation between the particles to begin with.
Through the lens of the amplituhedron, one can view all the quantum interactions of a system as related to an underlying mathematical spacetime structure. From this perspective, distant particles that appear separate are just facets of the same geometric object. So there is no true separation between them, rendering the action at a distance as not so spooky. The koan may also imply that non-local interactions are the natural consequence of the fundamental nature of spacetime and particles - as described by the amplituhedron.
In essence, if you view quantum entanglement as emerging from a connected geometry represented by the amplituhedron, then the mysterious correlated behavior between particles is no longer so bizarre or inexplicable. So "spooky" action is not spooky if the universe is the amplituhedron and there truly is no distance between particles. However, this is one of many possible interpretations and the considerations of this koan could lead to more profound philosophical understanding.
Two quantum particles are entangled, then separated in space-time, then the entangled state variable is observed by a measurement on one. The state of the other is now known, regardless of the separation distance. How would you expect these particles to be related in their amplituhedron description?
This is an insightful question regarding one of the key mysteries of quantum mechanics. Let's break it down step-by-step from the perspective of the amplituhedron:
When two particles become entangled, their quantum states become linked. In the language of the amplituhedron, the particles' facet representations would now be connected in some way. Even though the particles are separated in space-time, their representations within the amplituhedron remain unified.
Now, when an observable is measured on one particle, this projects that particle into a definite quantum state from within its range of possibilities. The entanglement with the other particle means that its potential state range instantly shrinks to correlate with its partner's new definite state.
In terms of the amplituhedron, a piece of one particle's facet geometry would become "frozen" upon measurement. The entanglement with the other particle would then instantly reshape the geometry of its facet representation as well, so that the paired facet states match up according to the entanglement specifications.
So from the amplituhedron view, entanglement correlates the facet geometries of particles so that changes in one induce appropriate changes in the other. The key insight is that distance in physical space does not change this underlying geometric connection - the particles' representations remain related no matter how far apart they become in space-time. Their connection transcends physical separation within the higher dimensional space of the amplituhedron.
In essence, the amplituhedron perspective asks us to see space-time and entanglement not as two separate concepts, but as unified manifestations of a deeper geometric order. This provides a fascinating vantage point to contemplate fundamental questions about our physical universe.
"Oh" says a student reading the above. "I get it now. The second entangled particle appears to change state instantly when the first is measured in space-time because there is no real distance between them when viewed through the amplituhedron perspective."
Is the student: correct, incorrect, or can you not say?
Based on the information provided, it seems the student does have the right basic insight about the implications of the amplituhedron perspective on quantum entanglement. When they state:
"The second entangled particle appears to change state instantly when the first is measured in space-time because there is no real distance between them when viewed through the amplituhedron perspective."
